According to a recent report by the Centers for Disease Control and Prevention[1], only 10% of Americans meet the recommended two to three cups of vegetables daily.

Although consuming a diet rich in whole foods is the best way to ensure your nutrient needs are met, adding greens powder to your diet can be highly beneficial. This is especially true if you have food aversions to leafy greens or limited access to fresh produce.

As the demand for greens powders continues to skyrocket, so does the number of products available. With so many options, how do you know which is best for you?

In this article, we’ll be reviewing the best greens powder supplements on the market today. We’ll also discuss the health benefits of greens powders and how to choose the right one for you.

Best Greens Powders In (October. 2022)

Are Greens Powders Good?

Over the past several years, many people have ditched their daily multivitamins in favor of greens powder supplements. Greens powders, also known as super greens, are dietary supplements made from dried greens, algae, fruits, digestive enzymes, probiotics, and more.

Like fruit and vegetable supplements, greens powders are an excellent option for those looking to fill nutrient gaps in their diet or who need an extra nutritional boost. Thanks to their high antioxidant content[2], they may also play a significant role in the long-term prevention of chronic diseases.

Who Should Not Use Green Powders?

Greens powders tend to be very high in vitamin K. If you are taking Warfarin[3] (coumadin), greens powder can significantly increase your vitamin K intake, decreasing your medication’s effectiveness. As such, you’ll want to work with your healthcare provider before taking them to find the best dose for you. It’s also important to stay consistent with your vitamin K intake after medication adjustments are made.

Additionally, compounds in greens powders such as wheatgrass and green tea may trigger allergic reactions in some people. People with food allergies should carefully check the ingredient label to ensure no allergens are present.

Pregnant and lactating individuals should also consult their healthcare provider before purchasing a green powder supplement.

9 Best Super Greens Powders of 2022

Athletic Greens

Athletic Greens is packed with vitamins, minerals, probiotics, and adaptogens, making it one of the most comprehensive greens powders on the market today.

  • Exceeds the recommended Daily Value (DV) for ten vitamins and minerals
  • NSF (National Sanitation Foundation) Certified for Sport
  • Decent taste
  • Includes adaptogens, probiotics, antioxidants, and digestive enzymes
  • Vegan-friendly
  • Proprietary blends used
  • Pricey

Since its debut in 2010; Athletic Greens has become one of the most popular greens powder supplements available. One 50-calorie serving delivers 75 vitamins and minerals, 2 grams of fiber, and less than one gram of sugar.

In particular, it provides over 100% of the recommended Daily Value for vitamins B6, B12, C, and E. This powder also contains many probiotics, digestive enzymes, adaptogens, and antioxidants.

Adaptogens[4] are active ingredients in plants that are known for their ability to combat stress caused by fatigue, depression, and illness.

Antioxidants[5] are also considered beneficial for our overall health because they help protect your cells against damage from free radicals, which are known to play a role in certain cancers and chronic diseases. They can also boost your immune system.

Because it uses proprietary blends, it is difficult to know exactly how much of each ingredient you’re getting.

Supergreen Tonik is packed with premium ingredients, including adaptogens, superfoods, vitamins, and minerals, to support your overall health and wellness. It is one of the best greens powders on the market today.

  • 365-day money-back guarantee
  • Third-party tested
  • Does not use proprietary blends
  • Flavor options available
  • Made in the USA
  • Lacks probiotics

Although Supergreen Tonik is not as well-known as other greens powders, it is one of the best you can buy. It is packed with 22 vitamins and minerals comparable to what you would find in a multivitamin. It also contains 38 plant-based greens and superfoods to support healthy energy levels, immunity, and focus.

For example, it contains ashwagandha root extract, known for its ability to reduce stress[6], enhance athletic performance[7], and fight inflammation[8] in the body.

This product also contains ingredients like garlic bulb extract, which some studies[9] suggest may benefit the immune system.

Supergreen Tonik is also free of dairy, soy, GMOs (genetically modified ingredients), caffeine, and toxins. It is available in mint and berry flavors.

Peak Performance Organic Green Superfoods

Peak Performance Organic Green Superfoods is an excellent choice if you are looking for an all-natural greens powder with an earthy flavor. It is the best organic greens powder available.

  • Physician developed
  • Free of artificial and refined sugars
  • 30-day money-back guarantee
  • Certified USDA Organic
  • Third-party tested
  • Natural, grassy flavor may not be for everyone
  • Composed of proprietary blends

Peak Performance Organic Green Superfoods is about as clean as green supplements get. It is United States Department of Agriculture (USDA) Certified Organic (at least 95% organic ingredients) and free of GMOs, gluten, and artificial sweeteners.

One 30-calorie serving delivers 2 grams of fiber and over 25 farm-fresh greens, whole fruits, and veggies. It contains an organic greens blend, digestive blend, glucose balance blend, garden blend, anti-inflammatory blend, and liver and detox blend to support total body health and wellness.

For example, it contains milk thistle[11], an antioxidant that works to fight inflammation. Although we need additional studies to verify its effectiveness, milk thistle has also been used for years to support healthy liver function. 

This product also contains barley grass, probiotics, prebiotics, digestive enzymes, kale leaf, and spinach leaf. Because of its digestive enzymes, it is one of the best greens powders for bloating caused by indigestion.

Peak Performance is also a proud supporter of Vitamin Angels, a charity that provides vitamins to moms and children at risk for malnutrition.

Spruce Greens

Spruce Greens

See Spruce Reviews

Spruce Greens is an excellent choice if you’re looking for a comprehensive greens powder with added ingredients to support a healthy metabolism. It is the best greens powder for weight loss.

  • Packed with 91 vitamins, minerals, and superfoods
  • May aid in fat burn
  • Made in the USA
  • Only 15 calories per serving
  • Vitamin profile is not listed
  • Uses proprietary blend

Spruce is a company initially known for its high-quality CBD oils, topicals, and gummies. Recently, they’ve introduced a green powder that will certainly not disappoint. Spruce Greens is sweetened with Stevia and packs in 91 vitamins, minerals, and whole-food sourced ingredients to help nourish your body from the inside out.

It’s also high in adaptogens to help combat stress and probiotics, prebiotics, and digestive enzymes to support your gut health. It contains 5 billion Lactobacillus acidophilus which is an effective dose range for probiotics.

Unlike many other greens powders, Spruce Greens contains a metabolism blend of green coffee beans and green tea extract, which contain caffeine. Studies[10] suggest caffeine can help increase fat oxidation or the process of breaking down fatty acids to decrease total body fat.

Currently, their website does not specify whether a third party has tested this product. However, it does say the product is thoroughly tested in the United States.

Skinny Greens Green Juice Superfood Powder

Skinny Greens Green Juice Superfood Powder comes in a delicious green apple flavor and is formulated with ingredients to support weight management, making it an excellent option for those who want to slim down.

  • 90-day money-back guarantee
  • Made up of 34 superfoods
  • Contains ingredients that may support weight loss
  • Affordable
  • Vitamin profile is not listed
  • No third-party testing

Skinny Greens is made up of 34 different superfoods, adaptogens, prebiotics, and probiotics to help fill nutrient gaps in your diet while promoting overall wellness.

As a bonus for those looking to slim down, Skinny Greens contains a waist-slimming blend made up of ingredients like glucomannan root extract[12] that may reduce appetite, promote satiety, and slow the absorption of sugar and cholesterol in the stomach, leading to blood sugar control and decreased cholesterol levels.

This product is sweetened with monk fruit and free of soy, milk, egg, and fish. However, it is manufactured in a facility that produces these allergens.

Unfortunately, it’s difficult to tell the amount of fiber, vitamins, and minerals in this product as it is not listed. It also lacks testing from a third party.

Live Conscious Beyond Greens

Beyond Greens is an excellent choice because it is affordable and contains energy-boosting ingredients without sacrificing flavor.

  • 1-year money-back guarantee
  • May improve energy levels
  • Contains adaptogenic mushrooms
  • Made in the USA
  • May not contain effective doses

Although Beyond Greens doesn’t contain as many ingredients as many other greens powders, it is still one of the best on the market.

With 14 different ingredients, the company says this supplement can help support healthy energy levels, immunity, and liver function.

It contains echinacea[13], which studies suggest, may reduce the risk of the common cold. It also has an adaptogenic mushroom blend that includes reishi, cordyceps, turkey tail, and lion’s mane. Collectively, these mushrooms may help fight off stress, increase athletic performance[14], support cognitive functions[15], and stimulate the immune system[16].

It is important to note that most studies are done using much larger doses than what is found in Beyond Greens.

This product also contains caffeine-containing matcha[17], which may help improve energy levels and fight inflammation. Although it contains probiotics, the content is much lower than what we usually see in competing greens formulas.

The website states the product is third-party tested, but it does not carry the certifier’s mark.

HUM Raw Beauty

Like other high-quality supplements HUM Nutrition produces, Raw Beauty Greens Superfood Powder is a solid option.

  • Formulated with over 30 superfoods
  • Mint chocolate flavor option
  • Third-party tested
  • Affordable
  • Contains added sugar
  • Uses proprietary blends

This powdered greens supplement is made up of over 30 superfoods, adaptogens, probiotics, and antioxidants in an easily dissolvable powder with a mint chocolate flavor.

With ingredients like spirulina[18] and alfalfa leaf[19], Hum’s Raw Beauty Greens can support healthy skin and fight damage from long-term exposure to ultraviolet rays.

It also includes adaptogens, including ashwagandha, Rhodiola, and astragalus. Studies[20] suggest Rhodiola can help prevent stress, fight inflammation, and fight early signs of aging.

Although it contains a fiber blend, one serving contains less than one gram of fiber, which is less than most competitors. It also only contains 6% of the recommended Daily Value for vitamin C, which is significantly lower than Athletic Greens.

However, this product is more affordable than others, costing just $39 for 30 servings. It is also free of artificial flavors, colors, and sweeteners, non-GMO, gluten-free, and tested by a third party for purity, strength, and composition.

Organifi Green Juice

Organifi Green Juice offers a unique blend of spirulina, moringa, adaptogens, and other superfoods to support overall wellness.

  • High-quality KSM-66 ashwagandha
  • May support energy levels
  • Third-party tested
  • Contains 3 grams of fiber
  • USDA Certified Organic
  • Lacks probiotics
  • Made of a proprietary blend

Organifi is already well-known for its red superfood powder. However, their Green Juice continues to rise in popularity. Formulated with six different greens and heavily studied KSM-66 ashwagandha, Organifi’s Green Juice is one of our top picks. 

This product also contains prebiotics to support a healthy gut, coconut water powder[21] to support fluid balance and hydration, matcha green tea to boost energy, and turmeric[22] to fight inflammation and support a healthy immune system.

It comes in both mint and crisp apple flavors and is USDA Certified Organic, Certified Gluten-Free, and Kosher. The company is also a proud supporter of Vitamin Angels.

Amazing Grass Green Superfood Alkalize & Detox

Amazing Grass Green Superfood Alkalize & Detox contains one full serving of fruits and veggies in every serving to help make up for deficiencies in your daily diet. It is the best greens powder for bloating.

  • Affordable
  • Ingredients that may support liver health
  • One full serving of fruits and vegetables
  • No sugar added
  • Gluten-free
  • Not third-party tested

This product is formulated with a green food blend, an alkalizing blend, a detoxifying blend, and a blend composed of digestive enzymes probiotics, and prebiotics. 

The detoxifying blend is composed of ingredients like organic beetroot[23] and organic dandelion root to support our liver, which is the body’s primary organ of detoxification.

One 25-calorie serving contains two grams of fiber and two grams of protein. It is also free of added sugars. It has small amounts of vitamins A and C and high amounts of vitamin K (28% DV). Because of the high amounts of vitamin K in this product, consult your physician if you are on any blood thinners such as Coumadin before taking this product.

This product does not appear to be tested by a third party.

How To Choose The Best Greens Powder Supplement?

Not all greens supplements are created equal. Moreover, the Food and Drug Administration (FDA[24]) does not test dietary supplements before they go to market, making it imperative to do your research before purchasing a greens supplement. 

Here are a few things to consider when choosing a green powder.

Third-Party Testing

One major concern with greens powder supplements is their levels of heavy metals. A greens supplement that is third-party tested is sent to an outside organization and tested to ensure it contains what the label says. It is also tested for unsafe amounts of heavy metals and other contaminants.

The most trustworthy third-party certifications are the National Sanitation Foundation (NSF), United States Pharmacopeia( USP), and ConsumerLab.

Ingredients

Greens powders can be expensive. As such, you want to be sure that the greens powder you choose is worth the cost. Consider choosing a USDA Certified Organic greens powder to ensure your product is as clean as possible. Avoid products with unnecessary additives, fillers, and added sugar.

Many cheaper powders contain fewer ingredients to keep costs low. The effectiveness of your greens powder will depend on the ingredients used and the amount in the product. Also, if you are seeking added benefits such as stress relief, choose a powder containing adaptogens.

Taste

If you find it extremely difficult to consume leafy green vegetables, you may not do well with an unflavored greens powder as many of them have a grassy taste. Consider reading customer reviews to help you find a good-tasting greens powder.

Health Benefits of Greens Powders

The specific benefits of a greens powder largely depend on its ingredients. However, most high-quality greens powders offer similar benefits due to their high nutrient and antioxidant content.

In addition to being a great way to fill nutrient gaps in your diet and supplementing a healthy diet with a boost of antioxidants and vitamins, greens powders may:

Improve Heart Health

Studies[25] show that eating leafy green and cruciferous vegetables can significantly reduce a person’s risk of heart disease.

Even if you are getting optimal amounts of leafy greens, it’s unlikely that you are regularly taking in ingredients such as the blue-green algae spirulina[26] which, according to studies, can decrease blood lipid levels and improve weight loss. Researchers suggest that people who supplement with 2-8 grams daily can reap these benefits.

One clinical study[27] also found that people who took greens powders for 90 days experienced a decrease in blood pressure.

Enhance Energy Levels

Many greens powders on the market claim to improve energy levels by adding nutrients your diet may lack.

Deficiencies in certain nutrients, such as vitamin B12[28] and iron[29], may result in fatigue. Therefore, supplementing with a greens powder that contains these nutrients may help improve your energy levels.

Some powders contain ingredients such as green tea, which can help improve energy levels.

Improve Immune Function

Most greens powders have high levels of vitamins such as A and C, which are known to support a healthy immune function.

Additionally, many contain probiotics[30], which can also support a healthy immune function by activating several immune mechanisms.

Final Thought: Is It Safe to Use?

Greens powders are safe for most healthy individuals as long as they are taken in quantities recommended by the manufacturer. However, many powders contain added ingredients such as herbs, adaptogens, digestive enzymes, and other nutrients that may interact with medications or may be contraindicated with certain health conditions. One such nutrient is vitamin K and its medication interaction with blood thinners.

Although many green powders contain probiotics, wheatgrass, algae, digestive enzymes, and other beneficial ingredients, studies are still limited on their benefits. You should never use greens powders to replace whole, nutrient-dense fruits and vegetables in your diet.

Always talk with your healthcare provider before taking any dietary supplements, including greens powders.

Frequently Asked Questions

Can I mix greens powder with anything?

Greens powder can be mixed with water, smoothies, juice, and shakes.

How often should I take green powders?

Greens powders should be taken once daily or as your healthcare provider recommends.

When should you use green powders?

Greens powder supplements can be enjoyed at any time of the day. Many people choose to add them to their morning smoothie

How to take green powders?

For optimal taste, we recommend making a smoothie using greens powder. You can add sources of healthy fat, such as avocado, chia seeds, and nut butter to help absorb the powder’s fat-soluble vitamins.

What are the precautions when consuming green powders?

People with existing health conditions, dietary allergies, and who take prescription medications should consult with their healthcare provider to ensure no interactions may occur. Pregnant or breastfeeding patients should also speak with their provider before use. Some people may also experience diarrhea from greens powder.
